There is a conflict between Event Espresso and Jetpack 2.0.4 that will manifest itself if either of the Publicize and Sharing modules are active. When either of these modules are active, opengraph meta tags get added to the head of the document, which are causing problems on the registration pages.

The problems may include a blank confirmation page, an error message on the payment page: “An error occured. The primary attendee could not be found.”, and duplicated attendee entries.

The Publicize and Sharing modules can be deactivated on the main Jetpack settings page by clicking the Learn more button, then clicking the Deactivate button that appears to the right of the Learn more button.

If you’d prefer to use either of these modules and you’re comfortable with working with PHP, you can remove the opengraph meta tags from the registration page by adding a function like this to a custom functionality plugin -or- if you have the Custom Files Add-on installed, you can add it to the custom_functions.php file:

function disable_jetpack_ogtags_on_regpage() {
    remove_action( 'wp_head', 'jetpack_og_tags' );
}
global $this_is_a_reg_page;
if ( $this_is_a_reg_page ) {
    add_action( 'template_redirect', 'disable_jetpack_ogtags_on_regpage' );    
}

There is an open ticket in our issue tracker to add a solution to the next version to avoid the conflict with Jetpack. In the meantime, the conflict can be worked around by disabling the Sharing and Publicize modules site wide or on the main registration page only.
